The electronic equipment is the cell phone jammer

When the cell phone inside the application place of cell phone jammer is in the status of calling or being called, the cell phone jammer will cut the signal connection between the cell phone and base station and stop the communication between the cell phone and the outside. And then the shielding of cell phone jammer has been achieved. When there is no communication between the cell phone and the outside, the    cell phone jammer will be in the detecting status and it will not send out any electromagnetic radiation. The power consumption will be reduced and the intelligentialization and environmental protection will be realized. The design adopts the intelligent interference as the guide of the design.
When people enjoy the convenience brought by the cell phone, they also will be influenced unfavorably by it. People will always interrupted by the ring of the cell phone in class, library or meeting room where tranquility is required. What’s worse, some people use imperceptibility of the cell phone and convenience of communication to cheat in the examination room where the fairness is needed. Therefore, it is hoped that certain electronic equipment can interrupt the communication between the cell phone and the base station so that the cell phone can not act. The working range of this kind of electronic equipment is normally the radius of about 20m. The electronic equipment is the cell phone jammer.

At present, the   china cell phone jammer in the market is designed on the basis of the method of the high power interference. The cell phone jammer should continuously emit the high power interference signal, otherwise it cannot work. However the high power electromagnetic radiation may do some harm to the human body. Therefore, it is necessary to design the intelligent and environmental cell phone jammer.
